Answer:

d. carboxyl

Explanation:

The presence of carbonyl group (>C=O)) and a hydroxyl group ( (−OH) on the same carbon atom is called a "carboxyl" group. A carboxyl group is represented as COOH and acts as the functional group part of carboxylic acids.

For example:

Formic acid or Methanoic acid (H-COOH)
Butanoic acid (C3H7-COOH)

Hence, the correct option is "d. carboxyl ".

Answer:

Part A. 10 atm

Part B. C₆H₆

Explanation:

Part A. At present, automobile batteries are sealed. When lead storage batteries discharge, they produce hydrogen. Suppose the void volume in the battery is 100 mL at 1 atm of pressure and 25°C. What would be the pressure increase if 8 × 10⁻² g H₂ were produced by the discharge of the battery?

We can find the pressure for this amount of Hydrogen using the ideal gas equation.

$P.V=n.R.T\\P.V=\frac{m}{M} .R.T\\P=\frac{m.R.T}{M.V} =\frac{8 \times 10^{-2}g \times (0.082atm.L/mol.K) \times 298K }{(2g/mol) \times 0.1L} =10atm$

Part B. A certain compound containing only carbon and hydrogen was found to have a vapor density of 2.550 g/L at 100°C and 760 mmHg. If the empirical formula of this compound is CH, what is the molecular formula of this compound?

First, we have to look for the molar mass of the compound through the following expression:

$P.M=\rho .R.T\\M = \frac{\rho .R.T}{P} =\frac{2.550g/L \times (0.08206atm.l/mol.K) \times 373.15K }{760mmHg} .\frac{760mmHg}{1atm} =78.1g/mol$

Now, we need the relation between the molar mass of the molecular formula and the molar mass of the empirical formula.

$\frac{78.1g/mol}{13.0g/mol} =6.01 \approx 6$

Finnally, we multiply the empirical formula by this coefficient to get the molecular formula.

(CH) × 6 = C₆H₆

Why do the two electrons spend their time equally between both hydrogen atoms? In other words, why can’t one hydrogen just take

vekshin1

Because it is a covalent bond meaning that they share the electrons to achieve full valence.

Honestly reporting experimental findings is an example of.. 1. ethics Or 2. Control

Hunter-Best [27]

Hello!

When you are honestly reporting experimental findings, you are using good ethics.

Ethics are moral principles that a person has, that allows for us understand and conduct certain behaviors. So when you are being honest, you are having good morals, or good ethics because you are sticking to the truth even though you could lie about your findings to get a certain result.

Hope this helps answer your question!
